How Exactly Do They Work?
Fire sprinklers are a part of a vital system that help protect your building against fire. They are a part of a complicated system and they can become even more complicated because there are numerous different types of systems. Fire sprinkler systems include:
- Wet Pipe Systems
- Dry Pipe Systems
- Deluge Systems
- Pre-action Systems
- Foam Water Systems
- Water Spray Systems
- Water Mist Systems
For this week’s blog post we will be focusing on Wet Pipe Fire Sprinkler Systems. Wet Pipe Systems are named for the fact that the fire sprinkler pipe is wet because there is constantly water on the system. They are also the most common type of fire sprinkler system.
How Do They Work
A Wet Pipe System is one of the most simple and reliable systems out there. This system works when the glass bulb inside of a fire sprinkler is heated to a specific temperature. This temperature can range depending on the fire sprinkler, but on average it is 155°F. The glass bulb is filled with a glycerin-based liquid that expands when heated. Once the liquid expands the glass bulb shatters. This breaks the plug and allows cold pressurized water to start flowing from the fire sprinkler pipe through the fire sprinkler head. Despite what the movies show, only the fire sprinklers subject to the proper heating will discharge water.
Pros and Cons
Wet Pipe Fire Sprinkler systems are not only the most reliable systems, but they are also the most cost effective to install. This makes them extremely common.
While these systems are great, they are only great in certain situations. For instance, because the water is constantly in the pipes it could be a freeze hazard in colder climates. In these situations a Dry Pipe System would be best. Or if you are protecting a building that cannot sustain water damage (server room, document room, etc.) then a Pre-action System or a gas clean agent system would be best.
